Tire-Mounted Refuse Bag Support with Adjustable Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
At outdoor events, unsecured trash bags are prone to being blown away by wind, causing litter, as they are inconvenient to carry and often not securely attached to nearby fixtures, such as vehicles.
Innovation Solution
A refuse bag support apparatus that includes a base member with adjustable pads and a collar, allowing secure attachment to a vehicle's tire, using compression slides and slide guides to maintain the bag in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unsecured bags are used, then ease of operation is improved, but reliability deteriorates because bags may be blown away by wind
Solution Approach 1:
The patent introduces a tire as an intermediary object between the refuse bag and the ground/vehicle. The base member clamps onto the tire, using it as a stable anchor point that prevents the bag from being blown away while maintaining ease of attachment. This resolves the contradiction by providing a reliable mounting solution without complicating the attachment process.
2Reliability
If a secure mounting system is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The base member incorporates movable pads that can slide along the tire surface and adjust to different tire sizes and positions. This dynamic adjustment capability allows a single device design to reliably mount on various tires without requiring multiple specialized components, thereby maintaining reliability while minimizing complexity.
Solution Approach 2:
The mounting mechanism changes physical parameters such as the position and distance between pads to adapt to different tire conditions. By adjusting these parameters, the device achieves reliable mounting across various scenarios without needing complex mechanical structures for each specific case.
3Adaptability or versatility
If adjustable pads are added to accommodate different tire positions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The base member is divided into separate movable pads that can independently adjust their positions. This segmentation allows each pad to adapt to the specific tire geometry and mounting location, providing high adaptability. The modular nature of segmented pads actually reduces overall complexity compared to a monolithic adjustable mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively secures a refuse bag to a vehicle, preventing it from being blown away by wind and ensuring convenient disposal of trash without additional user burden.
Implementation Method 1
a compression slide between the front pad and the rear pad for urging a face of the front pad towards a face of the rear pad
Implementation Method 2
a pair of parallel slide guides attached at a first end to the rear pad and extending through the front pad for guiding movement of the front pad relative to the rear pad

AI summary
A refuse bag support apparatus for use with a vehicle is provided. The support apparatus includes a base member having a frame and a first pad slidably mounted to a second pad, the first pad and the second pad oriented substantially parallel to each other and able to adjust to create space sufficiently large to permit a tire of the vehicle to be disposed between the first pad and the second pad to support the base member, and a collar mechanically coupled to the frame of the base member. The collar supports a refuse bag.
